Are you sure about that one? My father bought my old 18" OEM wheels from my first Titan from me. The hubs were different. The Titan wheels had a larger hub than the Chevy wheels did. I also checked it out when I was at my tire guy's place. He had a 16.5 wheel off a chevy lying around that I wanted to test fit on my truck. The hub opening on the chevy wheel did not fit opver the hub on my titan.
